Scientists around the world have tested some available pharmaceuticals to treat Covid-19 patients but were unable to prove the effectiveness of the drug.

There is currently no cure for Covid-19, so scientists are trying to use available antiviral drugs to test Covid-19 patients. Some drugs have been evaluated for effectiveness, but only in the early stages of research, others have been shown to be ineffective against Covid-19.

Explore from Canada

Recently, the Montreal Heart Institute (MHI, Canada) is said to bring a new ray of hope, when it released a press release on January 22 that the drug colchicine, often used to treat gout (gout), may relieves the complications of Covid-19. In the statement, MHI concluded that the rate of hospitalization (requiring mechanical ventilation) or death in Covid-19 patients taking colchicine was 21% lower than in those given a placebo. The study was performed with 4,488 patients in Canada, USA, South Africa and South American countries.
“This could be a real finding. However, I cannot trust the press release, ”says Ashish Jha at Brown University (USA). Some other experts point out that a study of colchicine used to treat people with heart disease previously found the drug had diarrhea and pneumonia side effects, but many experts expressed concern when MHI Just released a brief press release, with no detailed data released. MHI also does not publish research in peer-reviewed journals, which include cross-examination of industry experts, according to health news site Stat News (USA).

Many hope failed

Previously, experts cautioned when the news emerged that the antimalarial drug hydroxychloroquine could be used to treat Covid-19 because there is no clear scientific evidence, according to AFP. In July 2020, the World Health Organization (WHO) recommended not to use hydroxychloroquine in the treatment of Covid-19.

Countries strengthen entry restrictions

The United States yesterday joined France, Israel and Sweden to enforce immigration controls that have been in the UK, Brazil, Ireland, South Africa and most European countries recently, according to AFP . One day ago, France started asking people from EU countries to show negative test papers, while Sweden banned entry for people from Norway for 3 weeks.

In Israel, Prime Minister Benjamin Netanyahu declared a "sky closure" for flights arriving and departing within a week because of concerns about new variants of Covid-19. President Joe Biden's adviser, Dr. Anthony Fauci, warns that the new variant first discovered in the UK is more likely to cause death than the original Covid-19 strain. Besides, he also worries about the virus variant discovered for the first time in South Africa, which is believed to have a stronger potential for vaccine resistance. On the same day, Mexican President Andres Manuel Lopez Obrador confirmed that he had Covid-19.

HIV / AIDS medications have also been tested in Covid-19 patients. However, a study by the University of Oxford (UK) in October 2020 found that the HIV / AIDS drug does not work in Covid-19 patients.

Additionally, the United States allows emergency use of plasma from recovered Covid-19 patients for treatment based on promising preliminary research results, according to the BBC. However, experts believe that it is still too early to determine the effectiveness of this therapy. In addition, the experimental drug remdesivir has been approved or approved for urgent use to treat Covid-19 at about 50 countries by 2020. In November 2020, WHO made a recommendation not to use remdesivir to treat Covid-19 because there is no evidence that it reduces the risk of death and serious complications for patients. In the past, remdesivir has been tried in unsuccessfully in Ebola-infected patients.

In other developments, the WHO has warned of the danger that rich countries are over-stocking Covid-19 vaccine. However, there is good news that WHO and Pfizer (USA) have reached an agreement to supply 40 million doses of Covid-19 vaccine for the global Covax vaccine program.
